I am curious as to where Vale is at in regards to their exploration of the Trindade North tenement.
This is what I can gather.

August 2010 - Joint venture signed
April 2011 - Vale begins drilling
July 2011 - Vale has some positive drilling results
Sept 2011 - Vale sesures rights for a further year

So, have Vale been drilling on the tenement this year?.
Why would Avanco give updates on Vale in 2011 but not in 2012.
I hope I have missed something, as I do like this company, but need more info as to what is going on with Vale.
